@pichouk Is this something you’ve encountered before?

Nop. It seems related with letsencrypt process. Maybe when i installed certbot? @pichouk @amy.blais

It seems you already have an Nginx process that run on your server. Do you have any other webserver on the server ?

Thanks @pichouk. I fixed it. It was a web server on the host. It happend when i installed a cerbot support for ngnix.
